Abstract [en]

This paper presents a design teaching approach that aims to support students to shift their approach when exploring, prototyping and testing user interactions with physical products. This is conducted in a bottom-up, iterative manner to change the perspective from focusing on the opportunities of user-involvement during the form-giving process, rather than prematurely stressing the design outcome. Instead of emphasising on aesthetics and appearance, the design approach emphasises how users perceive, interact with and experience products. Through a series of workshops, apedagogical approach was developed for exploring and designing user actions with physical products, based on the notion of ‘action layers’. Action layers offer a mindset of designing, which facilitates understanding of, and design for, intuitive and tangible interaction. The approach builds on product semantics and emphasises cognitive and action-based paradigms to create intuitive and embodied information-for-use. Action layers present product interaction as a sequence of four steps; invite, engage, enable, and confirm. In the workshops, students iteratively explored form, prototyped and tested interaction with users through sketching with physical models, starting with minimal surface and edge treatments, eventually ending up with functional cues and meaningful form for a certain product type and environment. Through testing and evaluation, students learn to understand user behaviour, relate to their own expectations and intent to the design situation, and iteratively improve the design. The outcomes suggest that students advance their insights on how users interpret, respond to and interact with products, which consequently extends their ability to design products better suited for use.
